| dc.description.abstract | The rapid growth of the population resulted in an increase in the needs of life both in quantity and quality, while
the availability of land resources decreased and was very limited. Conflicting situations increase pressure on land
resources that are forced to produce as high as possible causing land damage including erosion. This study aims
to estimate the erosion rate and establish erosion hazard level (TBE) status on three land covers (secondary
forest, shrubland, open land). The time of this study was carried out for seven months effective, starting from
December 2021 to June 2022. The method used in this study is the stick method with a length of 1 m and a plot
measuring 20 m × 15 m as many as 3 plots, namely a measurement plot in a secondary forest, shrubs and open
land as well as soil sampling for soil physical and chemical properties. The results showed that the highest
erosion rate value in Lempake Village, Samarinda City occurred in open land, which was 1862,60 tons ha
-1
year
-1
,
and shrubs of 765,040 tons Ha
-1
year
-1
, included in class V (very heavy), while the lowest erosion rate value
occurred in secondary forests, namely 74,80 tons ha
-1
year, including in class III (currently). In connection with
controlling the erosion rate, it is recommended to apply vegetative methods such as planting legume cover crop
soil cover vegetation and enrichment of fast growing species. | en_US |
